Application filed May 13,

To all whom it may concern:

Be it known that 1. JAMES C. GOURLEY, a citizen of the United States, residing at artford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Machines for Shaping the Backs of Bookcases, ofwhich the following is a specification.

This invention relates to the type of machine designed for shaping the backsof boo-kcases or covers which is illustrated and de scribed in United States Patent No. 1,230,292 granted on my application June 19, 1917. In the machine of that patent the cases, which comprise two more or less stiff sides flexibly joined to a back, are stacked in a magazine which is adjustable to accommodate various sizes and which one at a time are successively removed from the bottom of the magazine and by an adjustable feed carried along between adjustable guides over a former and between adjustable creasers of the size and style to impart the required shape to the back of the cases. The feed mechanism shown in the patent referred to comprises endless chains carrying feed blocks that are adapted to in succession engage the edges of the lowest case in the pile and push it from the magazine to the shaping mechanisms.

It is frequently desirable for purposes of adjustment or inspection or the removal of a particular case and for other reasons to clear the feeding and shaping mechanisms without stopping the machine, that is, to run out those cases which are in the process of being fed and acted upon without feeding other cases from the magazine. The object of the present invention is to provide such machines with simple, quickly operated means whereby the feeding of the cases from the stack in the magazine can be stopped without interrupting the actions of the other mechanisms. v

This object is attained by arranging means in connection with the support that extends longitudinally of the machne beneath the magazine and over which the cases are carried by the feed blocks on the chains to the creasers and former, whereby the pile of cases in the magazinecan be. instantly lifted so as to raise the lowest case in the magazine above the plane of movement of the feed blocks and thus interrupt the removal of 1924. Serial No. 712,969.

In the accompanying drawings Fig. 1

shows :a plan of the portion of the machine to which the improvement is applied. Fig. 2 shows: a side elevation of the same. Fig. 3 shows, on larger scale, an end elevation of the machine. Fig. ashows a side view of the supporting bar and case lifting plates. Fig. 5 is'a planof the bar and lifting plates. I

The magazine for receiving the stacks of cases consists of two upright plates 1 that have their lower edges attached to the supporting bars 2 which are movably mounted on the frame bed 3 in such manner that by moving the bars in and out the plates of the magazine may be adjusted toward or from each other for accommodating cases of different shape and sizes. These bars extend parallel the lengthof the bed and are utilized to support the edges of the cases as they are fed through the machine. The bars also carry the wings 4. which guide the cases as they are fed along from the magazine. The supporting bars carrying the magazine and the guiding means are adjustable to ward and from each other by means of screw shaft 5, as more particularly pointedout in of -which is adapted toextend above the block sufficiently toengage the edges of the lowest case of the pile in the magazine. On the top of the bed between the channels which form the guides for the chain and feed blocks is a fixed bar 11 to the upper face of which is fastened the shaping former 12. As the cases are fed along by the blocks on the feed chains with their sides resting on the supporting bars and between the guide wings the backs travel above the former. The feeding mechanism carries the cases so that the edges of the backs pass between two creascr bars 13, as described'more in detail in the former patent.

In carrying out this invention, to each side of the central bar 11 which extends longitudinally. of the machine. beneath the magazine is applied a plate 14;" which is fastened so that it may be reciprocated longitudinally and be given a vertical movement. These plates near each end are de siralbly provided with slots 15 which have a portion incline-d and a portion horizontal, Fig. 4. Projecting from the central bar into these slots are pins 16. The ends of the plates are connected by across head 17 through an opening in which extends a hand lever 18' the lower end of which is by a -pintle '19 pivoted between ears 20 of a bracketthat is fastened to the frame of the machine. lVhe-n the handle ispulled outward-the co-operation of the slots in the plates and the pins projecting from the centralbaris such that the plates are drawn down to positions in which their" upper edges are substantially flush with the top of'the bar. lVhen thehandle is pushed inward the inclined sections of the slots acting on'the pins tends-to lift the plates and carry their edges above the level of the bar. lVitlr the handle pushed way in so that the pins extend through the horizontal sections of the slotsthe plates are held in their lifted positions. Duringthe ordinary operation 'of' the machine the plates are held down intheir lowest positions. When in these positions the pusher plates on the blocks attached to the feed'chains can'engage and push the lowest case from the stack in the magazine and deliver it unto the former between the creasers; Ifit is desired for any reason to interrupt the removal of any of the cases from'the magazine the handle is'pushed inand the plates lifted so as to raise the lowest case above the plane of movement of the pushing plates on the blocks carried by the feed chains. With the plates in'their raised positions no :ase will be fed from the magazine but the action of the other mechanisms of the machine will not be interrupted.

The invention claimed is 1. In a machine for shaping the backs of ,;book casesthe combination with. the maga- Zinc for retaining the cases, creasers and former for shaping the backs of' the cases and means for feeding the cases from the under side of themagazine to between the creasers and over the former, of means for raising the lowest case in the magazine above the plane of movement of the feeding means.

2. In a machine for shaping the backs of 'book cases the combination with the magazine for containing the cases, creasers, and former for shaping the backs of the cases and feeding blocks for engaging the lowest case in the magazine and fee-ding it between the creasers and over the former, of means for raising the lowest case in the magazine above the plane of movement of the feeding blocks.

3. In a machine for shaping the backs of'book cases the combination with the magazine for retaining the cases, creasers and former for shaping the backs ofthe cases and. means. for feeding the cases from the under side of the magazine to between the creasers andv over the former, of means for lifting the cases in the magazine and holding the lowest case above theplane ofmovement of the feeding means.

a. In a machinefor shaping the'backs of book cases the combination with the magazine for retaining the cases, creasers and former for shaping the backs of the cases and means for feeding the cases from the under side of the: magazine to between, the creasers and over the former, of vertically movable plates for raising the lowest case in the magazine above the plane of move ment of the feeding" means, and means for raising and lowering said plates.

5. In a machinefor shaping the backs of book cases the combination with the maga zine for retaining the cases, creasers and former for shaping the backs of the cases and feeding means for feeding the cases from the under side ofthe magazine to between the creasers, and over the former, of longitudinally .and vertically inovabl e plates for raising the lowest case in the magazine above the plane of. movement of the feeding means, and meansfor moving said plates longitudinally and vertically.

6. Ina machine for shapingthe backs of book cases the combination with the magazine for retaining the cases,creasers and former for shaping the backs of the cases and feeding means for feeding the cases from the under side of the magazine to between the creasers and, over the former, of a supportingbar, plates movably applied to said bar, below the magazine and pins and inclined slots connecting said plates to said bar, whereby the longitudinal movement of the plates with relation to the bar imparts a vertical movement to said plates.

7. In a, machinefor shaping the backs of book cases the combination with. the magazine for retaining the cases, and means for normally feeding the cases from the under side of the magazine of means below said cases for raising the lowest case in, the
